"Hmph-"

With a muffled snort, the mark in Du Fei's hand changed rapidly, and wisps of true qi quickly wrapped around his body, making the sharp pain on his body dissipate a little.

"Master, this Xuanbing Celestial Body is not cultivated like this! If you want to succeed in cultivation, the first step is to completely dissipate the true qi in your body, and let those rich Yanzong Qi completely cleanse your muscles and bones, and then produce some kind of change, this kind of suffering is naturally not small. However, if you can successfully cultivate this Xuanbing Celestial Body, the next time you attack the Martial Sect Realm, it is estimated that the success rate will increase a lot!" Looking at Du Fei, who was using True Qi to resist the erosion of Yanzong's Qi, Xiao Bai frowned slightly, glanced at the scroll in his hand, and then said quickly.

"Do you let the qi of Yanzong wash the marrow of the musculoskeletal?" Du Fei frowned slightly, but after a while, he still gritted his teeth violently, and the mark in his hand scattered, and the true qi that was originally wrapped around him also quickly retreated, and then, the flame-like Yanzong qi suddenly surged towards his body pervasively, this Yanzong qi like a flowing flame and slurry, the moment he entered the body, it made Du Fei almost roar in pain, and it felt as if his whole person was about to be burned to ashes.

"Master, as long as it's not the power of true qi, you can use it to fight against this Yanzong qi!" seemed to sense Du Fei's pain, and Xiao Bai was also fast.

"Why didn't you say it earlier?" Du Fei gritted his teeth fiercely, his whole body collapsed, and suddenly, he saw a golden color all over his body in an instant, making the musculokeletal muscles and bones of his body extremely strong, and at the same time, it also reduced the feeling of those hot and sharp pains a little.

However, after performing the bronze forging technique, this Yanzong Qi has become no longer too hot, and Du Fei can even clearly perceive that when these Yanzong Qi circulates in his body, it seems that something has been washed by them, and instead, there seems to be an extremely terrifying explosive power in his musculoskeletal.

It's just that this feeling is just a feeling so far, and if you want it to become real strength, I'm afraid you will have to pay a lot of price.

"Boom, boom—"

The incomparably rich Yanzong Qi in the sky was like a cloud, constantly tumbling, and in the center of the clouds, Du Fei had been wrapped in the center of Yanzong's Qi, and in the end, these Yanzong Qi had all turned into a flame.

"Bastard!"

The flames were blazing, causing Du Fei's body to tremble slightly, if he hadn't experienced a similar feeling when he was impacting the Martial Sect Realm, maybe Du Fei would not have been able to withstand it for a moment.

"Let's hope the master will succeed. Looking at this scene, Xiaobai also patted Xiaohu's head and quickly stepped back a little. Things have developed to this point, and there is no way for it to interfere, as for whether or not he can succeed in cultivation, everything depends on Du Fei's own fate.

............

The clouds formed by the Qi of the Yanzong were like a cloud dragon, constantly tumbling, and the flames of the Yanzong in the center of the clouds seemed to be burning forever.

And under this kind of burning, three days passed in the blink of an eye. During these three days, Du Fei would occasionally let out a roar of great pain, with the strength of his physical body, he would let out such a roar, you can imagine how tragic the torture he was at this moment. It's just that there is no other way to cultivate this kind of cultivation, cultivating the body forging martial arts is an extremely painful process, if the cultivation is successful, it will naturally increase its strength greatly, and if it fails, it will naturally break the meridians inch by inch and die in an instant. Du Fei is naturally clear about this kind of ending, but on the way of cultivating martial arts, which thing is not full of dangers when cultivating? If you want to become a strong person, in addition to talent, the more important thing is to put in more effort than ordinary people! There has never been a peak powerhouse in heaven and earth, who has come all the way smoothly!

Xiaobai's gaze was also quite worried, if it weren't for the induction of it and Du Fei, it clearly knew that Du Fei was still alive at this moment, it would almost think that Du Fei had turned into ashes.

"Whew-"

In Xiaobai's gaze, in the center of the flame, a white smoke suddenly rose, and then, a strange cold feeling, mixed with the continuous hot wind, swept out.

"It's ...... The extreme of the yang is yin, and the extreme of the flame is cold...... Forging yin with yang, taking cold from the flames......" Feeling this change, a faint hint of joy suddenly appeared on Xiaobai's face, and then he muttered.

"Boom—"

In Xiao Bai's surprised sight, the Yanzong Qi in mid-air suddenly surged wildly as if it had been teased by some kind of teasing, and then, this cloud dragon quickly surged towards the center of the clouds, as if trying to extinguish a wisp of chill in the clouds.

It's just that although these Yanzong Qi are violent, before those chills, it seems that they can't enter even half a step.

"Whew-"

Suddenly, a strange sound sounded, and in an instant, I found that a whirlpool seemed to appear in the center of the cloud, and suddenly quickly absorbed all the Yanzong qi into it, but in the blink of an eye, all the Yanzong qi that was originally all over the heaven and earth disappeared. At the same time, the figure that had been sitting cross-legged on the mountain peak also appeared in Xiaobai's sight again.

"It's ......"

At this moment, Du Fei's body was full of ice crystals, as if his body was made of some kind of cold ice, and at the same time, an incomparably cold aura diffused from his body, as if he would bring a blizzard just by breathing.

At this moment, the ice crystals on Du Fei's body are still changing color, but it seems that they are not stable and have not been able to change into the most critical color.

"It's... It's actually a lack of Yanzong's qi?"

Xiaobai stared at this scene deadly, and after a while, he was suddenly slightly stunned, and reacted instantly. It took a closer look at the scroll in its hand, and instantly understood. At this moment, Du Fei's cultivation has reached the most critical point, at this moment, as long as he has enough energy, he can inhale all the power of these ice crystals into his musculoskeletal, in this way, his Xuan Ice Celestial Body can be regarded as barely successful in cultivation.

But if this step fails, then all the efforts he has made before will be in vain!

At this moment, Du Fei is obviously in an extremely mysterious state, it is estimated that he himself does not know this, and Xiaobai cannot communicate with him for the time being. Therefore, after staring at Du Fei for a moment, Xiao Bai's little hand waved, and suddenly, he saw that among the black spirit rings in Du Fei's fingers, countless dense Yanzong Dan suddenly roared out like a tide!

"Buzz—"

With the appearance of these Yanzong Pills, Du Fei's body seemed to suddenly have a strange adsorption force, and then, the Yanzong Pills didn't even have time to explode, but he had already absorbed all the energy in them.

"Boom, boom—"

The incomparably thick Yanzong Qi was completely absorbed by Du Fei's body, and at the same time, a light blue pillar of light suddenly rose into the sky, and at the moment when this pillar of light appeared, a layer of faint ice crystals appeared strangely in a radius of dozens of miles around the entire mountain peak!

With the emergence of this cold air, the body sitting cross-legged on the mountain peak also trembled violently, and then, at a certain moment, the extremely cold power that originally erupted had been fully reined in!

"Yin and Yang Transformation, Hot and Cold Exchange, Xuanbing Celestial Body!"

The voice with a bit of mystical meaning sounded faintly, and then, I saw that among the peaks of the mountain, a brilliant light burst out in an instant! And the obvious degree of this light could be clearly seen even by people hundreds of meters away.

"Success!" Seeing this scene, Xiaobai also showed a happy expression. At this point, Du Fei not only absorbed all the Qi of the Yan Sect, but also turned Yang into Yin, at this moment, the power of his physical body would be unimaginably terrifying.

"Click-"

At the same time that the cold air was all subdued, the pillar of light in mid-air also slowly disappeared, and then, the body that had been sitting cross-legged finally slowly stood up!

Looking at the past from a distance, Du Fei at this moment has not changed much compared to before! It seems that the previous cultivation is fake, but with Xiaobai's eyesight, he can see at a glance that Du Fei's skin at this moment is so white that it is already a little similar to a woman, but it has no other thoughts about this scene. Because, Xiaobai understands that under this fair-looking skin, the physical power contained in it will be extremely strong!

At this moment, although Du Fei slowly stood up, he didn't make any other movements, just closed his eyes, as if thinking about something, and after being silent for a while, he slowly opened his eyes and showed a faint smile.

"Congratulations master, the cultivation has been successful!I just don't know how far the master's physical strength has reached!" Seeing Du Fei open his eyes, Xiao Bai couldn't help but smile lightly.

"Physical strength, try it and you'll know!" Du Fei smiled, and then the soles of his feet had already slammed on them!

"Boom-"

With his movements, the mountain peak under his feet instantly collapsed, revealing the dark mountain inside, and at the same time, in the mountain, an extremely powerful aura suddenly gushed out! It turned out that there was a hibernating demon beast hidden in this mountain, and judging from its breath, its strength actually had a half-step Demon King Peak Realm!

"Roar—"

As if he was very angry that someone had disturbed his cultivation, the demon beast roared into the sky, and then its body flashed, but it had already slammed towards Du Fei in mid-air.

Seeing this scene, Du Fei smiled, as if he had known that it would appear, and as soon as he stepped on the soles of his feet, there was not the slightest true qi surging on his body, but his body was rushing out in the blink of an eye, and almost instantly rushed in front of the demon beast.

At this moment, Du Fei's body was not as big as one of the demon beast's teeth, however, at this moment, he didn't make any moves, but his body turned in mid-air, and then his right leg was thrown out like a whirlwind!

"Boom-"

With one leg thrown out, the demon beast that was almost half a step away from being able to advance to the Demon King Realm made a loud noise all over its body, and it instantly exploded into a blood mist in the sky! Not even a trace of blood was left!

With a random blow, the demon beasts of this realm were blasted into powder, and such physical strength was unimaginably terrifying!

"Xuanbing Celestial Body! It's really terrifying!" Looking at the effect caused by his kick, the corners of Du Fei's mouth also set up a faint smile! At this moment, the strength of his physical strength, I'm afraid, can already compete with the powerhouses of the sixth-rank low-level martial sect! With such strength, even if he doesn't advance to the Martial Sect realm, he will probably be able to get a place in the battle of Kyushu!

As soon as he thought of this, even if he was as temperamental as Du Fei, he couldn't help but raise his head and laugh.
